International  Tractor  Disk  Harrow 

The  "One-Man"  Outfit 

FOR  tluirftiiylil.v  d<)ul)le-di.sking  a  large  acreage  in  a  short  time  there  is  no  implement 
that  t-in  compare  with  the  International  tractor  disk  harrow.     This  is  a  big,  strong, 
powerful  implement,   built  for  the  heaviest  kind  of  work  behind  a  tractor.     It  is 
built  in  two  sizes,  one  size  for  harrowing  a  strip  1(J  feet  wide  and  another  size  for 
harrowing  a  strip  12  feet  wide.      The  larger  implement  has  48  disks  divided   into  four 
gangs,  and  will  thorouglil.v  and  completely  douVile-disk  a  strip  12  feet  wide — and  when  this 
harrow  has  followed  the  plow  the  ground  is  almost  invariably  ready  for  the  drill. 

Trailers  Can  be  Used 

Spring  harrows,  peg  harrows,  or  seeding  machines  can  be  used  behind  the  Interna- 
tional tractor  disk  harrow.  A  strong  eye  is  provided  which  is  fastened  rigidly  to  the  rear 
of  the  tractor  harrow  frame.  It  is  a  great  time  saver  to  be  able  to  do  the  disking, 
smoothing  and  seeding  at  one  operation.  The  unusual  strength  of  the  International 
tractor  disk  harrow  makes  this  possible. 

This  is  a  "One-Man"  Outfit 

The  International  has  tlic  great  advantage  of  being  a  one-man  outfit.  The  man  wlio 
drives  the  tractor  operates  the  harrow — no  other  o])erator  is  needed. 

One  Hand-Wheel  Angles  All  Gangs   at  Once 

A  large  hand  wheel,  which  is  carried  close  to  the  operator,  in  the  cab  of  the 
tractor,  changes  the  angles  of  all  of  the  gangs  at  the  same  time.  This  hand  wheel  is  large 
and  convenient.  All  of  the  levers  which  it  operates  work  with  powerful  advantages, 
making  it  easy  for  the  engine  operator  to  change  the  angles  of  all  of  the  gangs  at  once. 
The  levers  and  rods  used  in  setting  the  gangs  at  their  proper  angles  are  of  amjile  size.

Strong,  One-Piece  Frames 

HE  frames  used  on  the  front  and  rear  ganys  are  practically  the  same.  Each  is  built 
of  one  continuous  piece  of  heavy  anyle  steel,  i-igidly  bolted  to  the  heavy  steel 
angles,  which  form  the  liacklione  of  the  hai-row.  The  corners  of  these  frames  are 
held  rigidly  by  flat,  steel  corner  braces. 

The  Gangs  Can  Always  be  Kept  Level 


The  front  gangs  are  held  level  at  all  times  by  the  heavy,  steel-angle  center  framing, 
while  the  rear  gangs  are  held  level  by  angle  steel  straps  which  act  on  the  angle  steel  cross 
braces  of  tiie  rear  frame.  The  gangs  are  i)ivoted  on  strong  pivots  located  back  of  the 
center  line  of  the  arbor  bolts  so  that  the  front  gangs  can  roll  together  on  their  l)um])ers, 
relieving  the  bearings  of  all  end  thrust.  The  pull  is  transmitted  to  the  gangs  by  heavy 
strap-iron  drawbars  working  over  large  spools  at  the  coiners  of  the  fraines.  By  this 
means  the  pull  is  applied  at  three  points  on  each  gang.  There  is  no  danger  of  bending  an 
arbor  bolt. 

Bearings 

All  of  the  bearings  used  on  the  International  tractor  disk  harrow  are  made  of  a 
special  quality  of  hard  iron  and  are  made  as  nearly  dust  proof  as  it  is  possible  to  make  a 
disk  harrow.  The  rear  gangs  are  built  with  a  thrust  bearing  on  the  outside  {which  is 
the  proper  location  for  a  thrust  bearing).  All  bearings  are  equipped  with  grease  cups, 
permitting  the  use  of  grease  (or  hard  oil)  which  is  the  most  satisfactory  material  for 
lubricating  an  implement  of  this  kind.  These  grease  cups  have  caps  which  are  made  to 
take  a  wrench.     Thus,  the  gi'ease  can  be  forced  into  the  bearings  in  cold  weather.

Forecarriage 

THE  Intcrnationiil  tractor  disk  h:irrow  is  roguhirly  equipped 
with  a  forecarriage,  which  is  of  great  value  in  keejiing  the 
harrow  running  steadily.  The  forecarriage  wheels  are 
fitted  with  grease  cups  and  dust-proof  lieaiings,  the  grease 
cups  being  located  between  the  spokes  where  obstructions  on  the 
ground  cannot  loosen  them.  The  forecarriage  wheel  axle  is 
swiveled,  iJermitting  the  forecarriage  wheels  to  follow  the  uneven- 
ness  of  the  ground.  The  forecarriage  is  of  especial  value  when 
the  tractor  harrow  is  used  after  the  plow. 

Scrapers 

All  of  the  disks  are  equipped  with  spring  steel,  one-piece 
scrai)ers,  each  of  which  can  be  adjusted  to  press  as  tightly  against 
the  disk  as  desired.     They  are  made  of  a  special  shape,  which  is 

particularly   well   adapted  to  keeping  the  disks  clean.     The  scrapers  are  held  in  place  by  a 

heavy  steel  angle,  which  is  firmly  bolted  to  the  gang  frame. 

Steel  Weight  Boxes 
The  International  tractor  disk  harrow  is  regularly  equipped  with  two  weight  boxes,   placed 
on  the  forward  gangs.     These  weight  boxes  are  made  of  steel  bars  and  angles.     They  are  of 
great  value  when  working  in  ditficult  ground. 

The  International  Disk  Harrow^  Gives  Satisfaction 

Tlie  International  tractor  disk  harrow  has  given  thoroughly  satisfactory  service  to  all  who 
have  used  it.  It  is  an  unusually  heavy  machine — one  that  will  get  right  down  to  its  work  and 
cut  its  way  through,  chopping  up  the  clods.  The  use  of  the  International  tractor  disk  harrow 
after  the  plowing  has  been  done,  with  a  spring  tooth  or  peg  tooth  harrow  trailing  behind,  and  a 
seeding  machine  behind  the  smoothing  harrow,  is  the  quickest  and  best  method  of  preparing 
a  good  seed  bed  and  gettmg  the  crops  into  the  ground  under  the  best  possible  conditions.
